Why can’t I get the DPS LED lights to go to the GREEN ZONE for the intraligamentary
Make sure the needle is being held in a steady position to allow the DPS adequate
time to determine the needle’s position within the tissue. If the problem
is that the LED lights are only part way up the scale, then the solution is to
advance that needle slightly, and hold the needle steady again to determine if
you’ve achieved a more optimal position within the PDL space.
Restart the injection using less force and lighter hand-pressure
while stabilizing the needle into the PDL space. Excessive hand-pressure
leads to the overpressure alert. With consistent use, you will quickly find
the optimal amount of hand pressure required to allow the back-pressure to
gradually build but which doesn’t cause the overpressure alert, due to the
DPS real-time feedback technology.
